HUB / BEARING
DESCRIPTION
The wheel bearing used on the front of this vehicle
is a unit type combined hub and bearing assembly
(Fig. 1). The hub and bearing is made up of the
wheel mounting hub (flange) and the wheel bearing.
The hub has five wheel mounting studs installed in
it. The hub is pressed into the bearing. It is held
together on the vehicle by the axle shaft and hub
nut.
The hub and bearing assembly is mounted to the
knuckle and is retained by four mounting bolts acces-
sible from the back of the knuckle.
The bearing requires no periodic maintenance. The
hub and bearing is serviced as an assembly if the
hub or bearing is determined to be defective. The
wheel mounting studs may be replaced separately if
necessary.
OPERATION
The hub and bearing has internal bearings that
allow the hub to rotate with the wheel and tire as
well as the axle shaft. The wheel mounting studs
allow the wheel and brake rotor to be mounted to the
vehicle.

DIAGNOSIS AND TESTING - HUB AND
BEARING (REAR)
With the wheel, disc brake caliper, and brake rotor
removed, rotate the wheel hub. Any roughness or
resistance to rotation may indicate dirt intrusion or a
failed wheel bearing. If the bearing exhibits any of
these conditions during diagnosis, replace the hub
and bearing. The bearing is not serviceable.
Damaged bearing seals and the resulting excessive
grease loss may also require hub and bearing
replacement. Moderate grease seepage from the bear-
ing is considered normal and should not require
replacement of the hub and bearing.
To diagnose a bent hub, (Refer to 5 - BRAKES/HY-
DRAULIC/MECHANICAL/ROTORS
-
DIAGNOSIS
AND TESTING).
REMOVAL
NOTE: Review all Warnings and Cautions. (Refer to
2 - SUSPENSION - WARNING).
(1) Raise vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)
(2) Remove wheel and tire assembly. (Refer to 22 -
TIRES/WHEELS - REMOVAL)
(3) Remove parking brake caliper and hydraulic
brake caliper from knuckle, and hang out of way,
then remove brake rotor. (Refer to 5 - BRAKES/HY-
DRAULIC/MECHANICAL/ROTOR - REMOVAL)
(4) Remove bolt fastening ABS wheel speed sensor
head to steering knuckle (Fig. 2). Remove sensor
head from knuckle.
(5) Remove cotter pin, nut lock and spring washer
from end of halfshaft yoke (Fig. 3).
(6) Remove hub nut and washer from halfshaft
yoke (Fig. 3).
(7) Remove plastic appearance cap from toe link
stud.
(8) Remove nut from toe link (Fig. 4).
CAUTION: When releasing toe link from knuckle
using Puller, Special Tool C-4150A, use care not to
pinch and damage grease seal.
(9) Release toe link from knuckle using Puller,
Special Tool C-4150A (Fig. 5). Remove tool.
(10) Remove cotter pin and castle nut from lower
ball joint stud (Fig. 3).
CAUTION: Do not strike or apply heat to steering
knuckle in an effort to separate ball joint studs from
knuckle.

NOTE: Use of Spacer, Special Tool 6983, is neces-
sary to allow proper use of Puller, Special Tool
C-4150A, to release lower ball joint from lower con-
trol arm.
(11) Insert Spacer, Special Tool 6983, between
lower ball joint grease seal boot and lower control
arm. Push Spacer in until it surrounds ball joint
stud. Use care not to damage grease seal boot.
CAUTION: When releasing ball joint using Puller,
Special Tool C-4150A, use care not to pinch and
damage ball joint grease seal boot.
(12) Install Puller, Special Tool C-4150A, over
Spacer and lower control arm as shown (Fig. 6). Ball
bearing in bolt of Special Tool C-4150A must be
centered in end of lower ball joint stud.
(13) Release lower ball joint from lower control
arm using Puller. Remove tools. Lift ball joint stud
from lower control arm.
(14) Install Puller, Special Tool CT-1003, on hub
and bearing flange (Fig. 7).
(15) Tighten Puller screw against halfshaft yoke,
pressing the yoke out of the hub and bearing assem-
bly.
(16) Pull outward on lower end of knuckle and
move halfshaft away from hub and bearing.

to knuckle.
(19) Remove hub and bearing from knuckle.
INSTALLATION
CAUTION: A corrosion prevention gasket is used
between the hub and bearing and the knuckle (Fig.
8). The gasket is required to prevent galvanic cor-
rosion between the hub and bearing and the
knuckle.
